El presente artículo tiene como objetivo mostrar, a través de un ejemplo, la elaboración de modelos digitales de precipitación (MDP) para 1'1 isla de Gran Canaria. Los MDP, como otros modelos digitales, permiten caracterizar con gran detalle la variable precipitación y se sustenta en técnicas de análisis espacial. Estas técnicas han tenido un gran desarrollo en los últimos años a partir del propio desarrollo de la inform5tica en geografía y, con ello, de los Sistemas de Información Geográfica (5IG). La importancia que cobra la isla de Gran Canaria en este campo, viene determinada por la gran cantidad de estaciones pluviométricas que se sitúan en la isla, logrando una densidad de red muy superior a la existente en otras partes del Estado.
One example of the realization of digital rainfall models in Gran Canaria is showed by this paper. These models, like other digital models, allow us to see in detail the observed variable (the rainfall, in this case) and is sustented by spatial analysis techniques, which have had a great expansion in the last years thorugh the expansion of computer techniques, and in special, the Geographical Information Systems (GIS). The importance of Gran Canaria in this field is due to the existence of a great number of rainfall observation stations in the island, what cause a high density, higher than in other parts of Spain.
